1942, Serial No. 433,397. In Belgium January 17 Claims. (Cl. 235-138) Myinvention relates to cash registers, and has for its primary object toprovide a cash register which is capable of carrying out all thenecessary or desired operations, whilst having an extremely simple andstrong mechanism, operated by a small number of parts, the manipulationof which is rapid and convenient.

Another object of the invention is to provide a cash register having aplurality of totalizers, scme of said totalizers (hereinafter calledgeneral totalisers) partaking in all registering operations, the othertotalisers (hereinafter called clerk's totalisers) partaking only incertain predetermined operations.

A further object is to provide a cash register, in which all thetotalisers are actuated by a single operating member adapted to effectboth the selection of the totaliser or totalisers to participate in theoperation to be registered, and the actuation of the totaiisersselected.

A still further object of the invention is to provide a cash registerhaving for each totaliser a carry-over mechanism, the carry-oversbecoming effective only on the intervention of a member independent ofthe operating member, thus permitting the correction of any error in aregisistration.

A still further object of the invention is to provide, in the cashregister, a travelling printing mechanism adapted to print checkingtickets after each operation and to print, when desired. the amountsaccumulated on any of the totalisers.

A still further object is to arrange the printing mechanism in suchmanner, that it cooperates with the totalisers in order to reset thetotaliser discs to zero.

This application is a division of my earlier application which haseventuated in Patent No. 2,282,120, dated May 5, 1942.

The cash register shown on the drawings comprises, from left to right onFigure 1, a general totaliser G, a daily totaliser Q, a first clerk'stotaliser A with operation counter A and a second clerk's totaliser Bwith operation counter B. It permits, for example, to registerseparately the operations of two salesmen on the totalisers A and'B, ofcounting the number of these operations on the counting mechanisms A 13,of registering on the daily totaliser Q all the operations carried outby the two salesmen in one day, and of registering the whole of theoperations of a week or of a month, for example, on the generaltotaliser G. Furthermore, an indicator I to the right of the registerindicates the amount of each operation.

The various totalisers and counters, as also the indicator, are eachconstituted by a gr p of annular discs ll, all identical, each providedwith ten teeth bearing the numbers to 9. Dis tance pieces ll separatethe groups of discs and prevent them from shifting in the axialdirection.

All the discs II are provided with axial bores and fitted freely on acommon shaft or spindle H which is mounted horizontally between abracket l3 and the right-hand side wall of the frame ll of the register,so as to be able to rotate in ball bearings. Bored out at II and I! atthe two extremities, this spindle I! has furthermore a longitudinalgroove ll of rectangular section in which is fitted a fiat bar ll forcedtowards the right by a spring ll fitted in the hollow II, and rigidlyconnected to the piston is by screws, said piston I! being adapted toslide in the hollow part I! and having a projecting rack 1|.

Under the action of the piston ll in one direction, and of the resettingspring II in the other direction, the bar II can slide axially in thegroove I! of the spindle l2, executing a step-bystep movement controlledby an escapement which comprises the rack II with circular teeth and twopawls Ii, 22 shown in detail on Figures 13 and 14. Each axialdisplacement of the bar, permitted by the escapement, corresponds to thedistance from center to center between two successive discs ll adjacentto each other of the totaliser. This bar i1, movable axially in thegroove it of the spindle I2, is also movable angularly with this spindleand it constitutes the operating member of the discs.

The bar l1 and yoke are connected in the manner representedin Figs. 1and 3. Yoke 23 comprises two plates 23a and 23b screwed together (Fig.1). A small pm No carried by bar n (Fig. 3) engages in a circular groovebetween the two plates of the yoke, so that the bar 11 may be rotatedwith respect to yoke II, while the bar and yoke are locked together asregards axial movements.

In its axial movement, the bar I! carries with it by the yoke 23 a setof pawls 24 (Figs. 1, 1'7 and 18) engaging yieldingly with the teeth ofthe totaliser discs it. Each pawl is provided with an ye 2!, and saidpawls are fitted side by side by their eyes on a sleeve 2. axially rigidwith the yoke 23 and adapted to slide on a fixed spindle 21 parallel tothe spindle II. The set of pawls 24 constitutes the means blocking thediscs.

The bar I! and the set or comb of pawls 24 are axially/movable togetheras a unit the set of pawls of the unit moving on the outside of thetotaliser discs ll whilst the bar i1 moves inside the discs [land canfurthermore rotate together with the spindle i2 about the axis of saidspindle.

The walls of the bores of the annular discs ll are each formed with arim of notches comprising ten round holes 1! each communicating by aconstricted neck 29 (Figure 19) with the central open part of the discfilled by the spindle i2. Due to the pawls 2 enga in with the teethaseeoss tudinal free face of the bar l1. These buttons I. have aspherical head adapted to the diameter of the holes I. of the discs II,a restricted neck beingabletopassintherestrictedpartofthese holes and acylindrical body fittet in a recess of the bar l1.

There is a button 30 on the bar I! for each totaliser (3, Q. A. B, andfor the indicator 1. The three buttons 38, 30, II of the generaltotaliser G of the daily totaliser Q and of the indicator I are fixed inthe bar l1. The buttons 30, I. of the clerk's totalisers are adapted todisappear in their recesses ii; against the action of a spring 32(Figures 15, 16). This disappearance is necessary to permit theselective control of one or the other of the clerk's totalisers A, B.

The selection is efiected'by means of a special arrangement of the fixedparts II, II (Figures 15, 16), serving as selectors, which are at theright of the partial totalisers (Figure 1) and comprise each a circularchamber II of less depth than said selectors, the bottom of saidchambers having a rim of holes ll, 2., respectively (Figures 15, 16)registering with the holes 2. of the totaliser discs. Some of theseholes. which are differently located in each selector, are replaced byone or more larger notches, in the form of arcs. The selector llcomprises a single notch 34 occupying the place of two successive holes,whilst the selector ll comprises two notches 35, it each occupying theplace of one hole and leaving between them a hole 20 Figures 16a, 16band show the constructional details of one of said selectors, i. e.selector B. As shown, the selector comprises two parts of equal width ordepth, one "B being a circular chamber of such diameter that the button"B in the projected position may turn therein freely, the other portionor chamber having a diameter equal to the diameter of shaft II, withholes ll arranged around its periphery except where they are replaced bynotches 3!, 30 (Figs. 16!), 160). The selector HA (Fig. 15) is ofidentical construction, except in that it has one notch 34 instead ofthe two notches it, It of selector MB.

In its inoperative position, the bar I1 is at the end of its travel tothe right (Figures 1 and 18), and the buttons III and II projectvertically (from said bar into the chambers respectively, and face thenotches I4 and 15, respectively.

To select a clerks totaliser, it is necessary to shift the actuating barI! first axially towards the left to cause the buttons 3M, ll to enterrespectively the notches 34,15 in front of them, and then angularly by atenth of a turn in clockwise direction if it is desired to select thetotaliser A, or of two-tenths of a turn in clockwise direction if it isthe totaliser B which is to be selected. It is thus necessary to rotatebar ll through a predetermined angle in order to permit either button30A 01 button "B to project into a notch (respectively 34 or I), beforethe next axial movement of bar ll takes place. Only that button whichhas come out of the recess 3| can, during the axial movement of the bar,engage the holes 28 of the totaliser corresponding thereto and rotatethe discs of said totaliser. After a tenth of a turn, in fact, thebutton ll remains projecting in the wide notch and can thus be engaged,by a later axial movement of the bar IT, in one of the tunnels formed bythe holes 20'of the discs l0 of the totaliser A, whilst. the button 30has been forced back into its recess II by th arcuate wall of the notch00, and remains hidden during the later axial displacement of the bar H,the narrowness of the constricted necks 29 preventing it from leavingits recess to engage in the holes 20 of the discs of the second clerkstotaliser B. This latter is therefore eliminated while the totaliser Ais selected. In other words, the button which has not entered a notch(34 or II) of its selector. but was pushed back into the recess II isheld in said recess during the whole operation, because the necks 29 ofthe holes 20 are too narrow to enable the button entering any of saidholes.

If, however, totaliser B is to be selected, then the bar I! is rotatedthrough two-tenths of a turn. At the end of this angular movement thebutton 30A is pressed back into the recess ll by the curved side ofnotch 34, whereas button 303 stands in the middle of notch 30 where itprojects freely. Thus during the subsequent axial movement of bar I1,the button 303 will be engaged in the holes 20 in the discs of totaliserB and said totaliser B will be selected while button A will remainhidden and totaliser A will not be operated. Thus, the second clerkstotaliser B is selected. It is clear that in this way up to nine clerk'stotalisers could be selected by causing the bar II to rotate bynine-tenths of a revolution, provided that each clerks totaliser werefitted with a selector ll having suitable notches.

Since the general totalisers G and Q partake in all registeringoperations, there is no selector co-operating with said totalizers. Thedistance pieces ll adjoining the totalisers G and Q and the indicator I(Fig. 1) are annular spacing rings fixed on shaft l2 and havin peripherya longitudinal groove adapted to receive the corresponding buttons 306or "Q respectively, whatever be the angular position of the latter or ofbar II.

To effect the selection, the operating member l1, in the example shown,is manipulated by the operator by means of a key 31 (Figures 2, 7 and7a) the T end 31 of which engages in the slot 20 at the extremity of therack 20. This key has two webs or bits, the first of which 80 is narrowand parallel to the wings of the T, and the second 39 is wide and offsetwith respect to 30 by an angle corresponding to one or twotenths of arevolution according to whether it is a question of the key of thetotaliser A or of that of the totaliser B. It is clear that theoffsetting can run, for example, from 1 to 9 tenths of a revolution fornine different keys, if the register comprises nine clerk's totalisers.

There is made in the outer wall 40 of the register, a vertical keyholell for the passage of the key (Figures 1 and 7). When the key is ininserted, its end 01' only comes into engagement with the slot 205 atthe end of the rack 20 when the web or bit it, placed vertically, entersthe hole ll. On continuing to insert the key, the operator pushestowards the left the rack 20 and the actuating bar l1. thus engaging thebutton I0 30 into the notches 34, 35 of the selectors II H The secondweb 39 then abuts against the surface 40 and can only enter the hole llafter the operator has turned'the key by a tenth of a revolution if itisthe key of the totaliser or by two-tenths of a revolution if it is thekey each at their innerin the set, and is replaced by of the totaliserB, thus causing the bar I! to rotate with the spindle l2 by the anglenecessary to select the desired totaliser A or B.

It will thus be seen that the web 30 enters hole ll when the end 31' ofthe key comes into en'- gagement with the slot 20' at the end of rack20. The key then is inserted further and it is turned only when thesecond web 39 abuts against the wall 40. Then the web 08 is clear ofsaid wall and the key may be rotated.

It will be understood that this rotation of the bar II with the buttons30, 30, 30, 30 and 30 has no action upon the totaliser discs since,during this rotation, all'the buttons are engaged in the distance piecesII and selectors H, II, respectively, and not in the holes 28 ofanytotaliser discs.

The operator can then fully insert the key and thus press the bar I! tothe end of its travel towards the left, which has for effect toengagethe driving buttons 30, 30, 30, or 30 and 30 respectively in thegeneral totaliser G, the daily totaliser Q, the clerks totaliser A or Bselected,

and the indicator I.

Actually the whole selection operation of the totalisers is reduced, forthe operator, to inserting in the hole 4|, and pushing and rotating thekey of the totaliser which he desires to select. A stop 42 arresting theweb 39 opposite the hole ll avoids any groping. The general totaliser Gand the daily one Q having to register all the operations of the cashregister, do not give rise to selection.

After selection of the totalisers and complete displacement of the bar Hto the left, the key 31 is fully withdrawn so that the bar l1 togetherwith the shaft l2 and discs l0 may rotate.

The axial displacement of the bar H to the extreme left under the thrustof the key 31 causes a corresponding displacement of the set of pawls24, the pawls of which slide laterally over the teeth 'of the discs to.It will be noticed (Figure 1) that, in the plane of each driving button(30, 30, 30', 3|.) and 3'0 one pawl is missing a spacing ring 43 alittle wider than a disc W. This permits the individual discs I0 whichare at the moment engaged by the driving buttons to rotate withoutresistance, whilst all the other discs i0 are normally blocked by thepawls.

The unit ll-N is held in the extreme left-hand position, against thetensicn effect of the spring l0, by the pawl 21 which engages with thelast circular tooth adjacent the slot 20' of the rack 20. In thisposition the mechanism is ready to register an operation. To effectthis, the operator allows the unit l|-24 to come back stepby-steptowards the right (Figure 1) in order to bring each button 30successively in engagement with each of the discs in of the totaliser inwhich this button is engaged. At each stoppage of the unit l|--24produced by the engagement of a fresh tooth of the rack 20 with the pawl2|, the operator rotates the bar H with the spindle I2 by a, number oftenths of a revolution corresponding to the number of units to beregistered in the numerical order allocated to those of the discs I0 inengagement with the buttons 30 at the moment in question. These discsbeing opposite spaces in the set of pawls 20, are free to rotate at thismoment. but are blocked immediately afterwards by the following pawlswhen the forward movement of the unit i|-2l brings the buttons 30 intoengagement with the following discs. or a lower numerical order in theselected totalizers.

when the operator, aiter entering the last digit of an item (which isthat of the lowest numerical order) allows once more the unit ll-N toreturn to the right, there are no more teeth on the rack 20 to beengaged by the pawl ii, and the spring ll brings the bar il back to itsinitial extreme right-hand position (Figure l), with the driving pins"A, "B within the respective circular chambers "A, "B.

An example will now be given, showing the manner in which the wheels IIare operated to add items.

Let us suppose the amount to be registered by the general totalisers Gand Q and the totaliser A is 349.00. 'I'otaliser A having been selectedas explained before. the bar I! is moved to the left as far as it can go(Fig. 1), its buttons 30 are engaged in the "hundreds discs oi all theoperative totalizers. The operator then lowers handle ll pivoted at 4!through three divisions along scale is (starting irom the verticalposition shown in Fig. 13), and by doing so he turns, through threetenths of a turn, shalt I! with bar ll, buttons 3| and the discs lengaged by said buttons. Movement of the handle 44 is transmitted to theshaft I! through a pawl 40 engaging the teeth of a toothed wheel 41which latter meshes with a toothed wheel 4| keyed on the shaft l2. Whenhandle ll is then raised towards or beyond the vertical position, theangular position of the discs I! is not altered, as the pawl ll (Fig.13) idles over the teeth of the wheel 41 without rotating either saidwheel or the pinion 48. By pushing handle it beyond the verticalposition, the operator produces an escapement of bar H by one steptowards the right, as hereinafter described, the result being that thebuttons 30 leave the hundreds discs and come into engagement with thetens discs. Having brought the handle 44 back to vertical position, theoperator now lowers it through four divisions along scale "a, wherebyall the "tens discs are rotated through four tenths of a turn. Again theoperator moves the handle beyond vertical to produce a furtherescapement of bar 41 by one step, thus bringing the buttons 30 intoengagement with the units" discs. Then handle 44 is lowered through ninedivisions along scale "a, thereby rotating the units discs through ninetenths of a turn. Finally, the handle It is twice pushed backwardly tocause two escapements whereby the discs II in th two decimal placesremain in zero position. The desired number 349.00 thus is set up in allthe operative totalisers, that is to say, in all the totalisers exceptthose in which the buttons ll were pushed down during the selection.

Supposing the operator now has to add the number 23.00 to the number349.00 previously registered. He does not have to bother about theangular position of the discs ll, because whatever be their positionresulting from previous operations, the holes 28 in adjacent discsalways form around shaft l2 ten tunnels in any of which the projectingbuttons may travel. First the discs of the indicator I are released forrestoration to zero and the unit "-24 which is now shifted completely tothe right is turned upon actuation of the member ll under the influenceo! the spring 56, which operations will be hereinaiter described, untilthe slot 20' is restored to its initial vertical position. Again thedesired totaliser is selected, and bar I1 is moved as far assaoea aspossible to the left by means As there are no hundreds to be registered,the handle 44 is pushed backwardly to produce an escapement and to bringabout the engagement of the tens discs by the buttons III, the"hundreds" discs remaining in set position. Then handle N is loweredthrough two divisions of the scale to rotate the "tens" discs throughtwo tenths of a revolution, the handle is moved back and after a furtherescapement, it is lowered through three divisions to rotate the "unitsdiscs through three tenths 01' a revolution. The handle 44 is againswung rearwardly twice so that the discs II in the two decimal placesremain in set position.

After each registering operation. the operator rotates shaft 10 by meansof crank II in order to complete the carry-over of the tens, whichcarry-over was prepared in the course of the registering operation aswill be described in greater detail hereinaiter.

when the handle is pushed back beyond the vertical position shown inFigure 13, it releases the escapement of the unit "-34 by acting on theescape pawls ll, 22, already mentioned, and arranged on each side of therack 20 with which they co-operate. When at rest, the pawl 2! engaseswith the rack and the awl 22 is disengaged therefrom. For thedisengagement, a boss 44' of the handle-forces the pawl 22 intoengagement and disengages the pawl II, the operation being eflected bythe pawl 22 striking a projection 40 of this pawl 2 I The pawl 22 ismovable along its axis 50 (Figures 13, 14) over a distance equal to onetooth of the rack. Liberated from the pawl 2| the rack driven by theunit "-24 moves with it by this distance carrying with it axially thepawl 22 until this latter stops against the head ii of the spindle Bl.It the handle 44 is then brought back into the vertical position, aspring it replaces the pawl II in engagement with the rack, whilst thepawl 22 is disengaged therefrom by a spring II and is drawn back by aspring 54 (Fig. 14) into position for a fresh escapement. The completeescapement can be produced by bearing directly on a driving member II 01the pawl 2 I, thereby disengaging the latter from the rack II, the pawl22 being held inoperative by the spring 53.

After each escapement whereby in each totaliser the corresponding button30 has been brought into engagement with a fresh disc ll of a lowernumerical order to the preceding one, the operator can lower the handleIt to cause the rotation of the discs in engagement with the desirednumber of tenths of a turn and then put back the handle to eii'ect afresh escapement, and so on.

The lowering oi the handle 44 and the consecutive rotation of the smallwheel ll cause the rotation in the direction 01' the arrow (Figure 13)of a large toothed wheel 5 urged in the reverse direction by a spiralspring IO. After the lowering of the handle, a pawl ll retains the wheel4| against the action of this spring It. If the pawl II is disengaged bydepressing its operating member II, which is integral with" and whichturns about the axis 51, the spring 50 causes the counter-clockwiserotation of the small wheel ll, with the spindle it, the pawl ll of thewheel 41 then resting against a fixed stop I! and being disengaged fromthe wheel 41 which can thus rotate with the wheel ll without carryingthe handle 44 with it in clockwise direction beyond the positionrepresented in Fig. 13. Clockwise rotation of the wheel II will thusrotate the wheel assaoss l1 and handle 44 clockwise until the handle isslightly beyond the, position shown inFig. 13 when the pin 59 will actto disengage pawl 46 from wheel 4'! and thus liberate M from any furtherclockwise movement. It is advisable, however, to put the handle beyondthe position shown in Fig. 13 before disengaging the pawl 51 bydepressing 58. This manipulation permits in particular the operator tocancel or correct a wrong manipulation of the handle ll, having had foreflect to impart an incorrect number of tenths of a turn to the discs I!at the moment in engagement with the buttons 30.

When cancelling a wrong manipulation, the backward rotation of wheel I!and of shaft I! with bar I] will be stopped at the moment when theincorrectly actuated disc is reset to zero, owing to the followingarrangement: The discs Ill of the printing mechanism are normallyengaged by the indicator discs I0. When, after an operation which is tobe cancelled,- the spring 58 is permitted to rotate the wheel 48backwards, and with it the bar I1 and those discs ill including anindicator disc which are engaged by projections 30, the said indicatordisc rotates the corresponding wheel I01 of the printing mechanism untilits pin I08 (Fig. 21) is stopped by the finger I09, which happens whenthe discs involved are at zero.

As above stated, each lowering of the handle 44 can impart up tonine-tenths of a turn to the spindle l2, and consequently to the discsin in engagement with the buttons 30. The capacity of rotation of thewheel 55 from one side to the other of a stop piece 60 which it strikesagainst at the ends of its travel through a spur piece 6i, musttherefore be equal to the rotation due to the key 31 plus as many timesnine-tenths of a rotation of the spindle I! as there are teeth in therack 20, since the latter determine the number of positions of the unitlI-fl for which the handle 44 can impart a movement, up to ninefrom zeroeach operation. The operator can thus check in the mirror whether theamount shown is really that which he has desired to introduce into agiven digital and, in case of error, he can correct by means of the pushmember ll as described above. In other words, the indicator discs beingcontrolled by a button 30 which is not collapsible, the indicator willregister each item entered in any one of the totalisers, starting eachtime from zero. The operator thus is enabled to check from the indicatorthe correctness of each figure in the amount registered, and also tocorrect any mistake as already pointed out.

. Up to the present, the general operation of the totalisers and theircontrol by the manipulating mechanism which permits of the simultaneousrotation by the desired amount of the discs of tenths of a turn, tosuccessive discs ill in each totalizer. In other words it will be seenin Fig. 13 that all the rotational movements of spindle I! aretransmitted to the toothed wheel 55, which can rotate through an angleoi almost 360, limited by the pin 6| striking on one or the other sideof abutment 60. Supposing we have to register the highest number whichis 999.99 in the constructional example illustrated, then wheel 55 mustbe able to turn with pinion 49 while said pinion, together with shaftl2, rotates through five times nine tenths of one turn. But previously,when the selecting operation was performed by means of key 31, the shaftI! with its pinion ll had already effected a partial rotation (1. e. onetenth of a turn if totaliser A was selected, or two tenths of a turn iftotaliser B was selected) and this initial rotation had also beentransmitted to wheel 55.

It is thus made possible by actuating the single handle ll of themanipulator for the operator to cause the successive rotation of each ofthe discs I. of each totaliser to introduce into the latter the desirednumber of units of each numerical order for example of the hundreds,tens, units and decimal fractions of units. At the same time as thediscs I! of the different total! isers, and the discs III of the samenumerical order of the indicator l are also rotated by the same amount,and they cause the appearance in a mirror 62 of an amount which is thatof the operation being carried out, the indicator starts the samenumerical order in the diflerent totalisers, has been explained. Inaddition to these movements eflected ositively, there are produced inthe totalisers automatic movements for the carry-over of the tens ofunits of the discs of a numerical order to the discs of the highernumerical-order. The carry-over of the tens is prepared automatically,in each totaliser, but it only becomes operative on the manipulation ofa control crank common to all the totalisers,'which permits ofcancelling a carry-over arising from an incorrect item entry in a givenorder when the erroneous entry is cleared as long as the crank has notbeen actuated.

The mechanism preparing for the carry-over comprises fiat rings ll,arranged on the spindle I! where they alternate with the totaliser discsIll, each of said rings being fixed to the disc ll located immediatelyto its right. One of these rings 63 is shown dotted on Fi ure 17 behindthe disc III to which it is fixed, which disc on Figure 18, is to itsright. It comprises a ring of holes corresponding to the holes II of thedisc, and it has on its periphery a notch 64 and a nose piece disposedbehind the notch.

When the disc ll to which the ring I is fixed has rotated by nine-tenthsof a revolution from the zero position, in clockwise direction, (Fig.1'1) a finger 66 which was pressed downwardly on the edge of the ring bya stop 61, enters the notch 64 and is carried along. on the followingtenth of a turn of the disc, by the nose piece '5 which causes it torock about its axis 69 beyond the plane passing through the centres ofthis axis and of the spindle It. In this position of the finger 86, aspring I is tensloned and presses the finger against the ring, but thistime up-' wardly. The finger 86 remains in this position as long as thering I continues to rotate with its disc It in clockwise direction. Butif the disc and the ring are rotated in the contrary direction, forexample in order to cancel a wrongly formed figure, as explained above,the finger 68 enters the notch 04 when it comes opposite it. The ring 03then carries it along until above the line of the centres of the spindlel2 and the axis 69, and its spring returns it into the initial position,which nullifies the preparation of the carryover.

On the finger 68 there is fixed, opposite the next higher order disc il,a piece Ill carrying a tooth II, a projection 12 and a counter tooth orprojecting portion 16. In the raised position of the finger, the part IIthroughits counter tooth It bears against the stop 6] but when thefinger has been rocked by the nose piece II to prepare the carry-over ofa unit to the following disc ll,

the projection 12 comes into the path of a crossarm 13 mounted on aspindl 14 adapted to be actuated by the crank or handle I! of theregister. The carry-overs are thus prepared in each totaliser in thecourse of each operation.

When, after having effected the operation, the operator rotates thehandle 15, the arm I! is rotated in clockwise direction (Fig. 17 by thespindie 14 and strikes the projection 12, causing the rocking of thepart ll, the tooth ll of which engages between two teeth of the disc illto which the unit is to be carried over, and causes this disc to berotated by a tenth of a turn. To avoid the disc rotating further byinertia, the counter tooth 16 of the part I blocks the disc immediatelyafter it has rotated through the desired angle. All risk of error in thecarry-overs is thus avoided.

The spindle ll carries an arm 13 for each totaliser disc, and thesuccessive arms are displaced angularly by 90 so as to actuatesuccessively the parts of the successive discs of the same totaliser, inorder that the carry-overs may be effected from one disc to the otherwithout omission. The arms 13 carry out three rotations for tworotations of the crank 15. The transmission is effected by gearsarranged on the lefthand side of the casing, that is to say, a smallpinion I1 keyed on the spindle 18 of the crank (Figures 9 and 12), apinion 18 of double the diameter Joined to a larger pinion 90 and asmall pinion 9| keyed on the spindle 14 of the arms 13.

A little before the end of the movement of the crank a cam a2 (Figs. 8to 12) driven through shaft 21 by the pinion 90 acts on an arm of anelbow lever 93 which it causes to oscillate about the-axis H. The otherarm of the lever '3 carries the stop 61 and the axis 68 of the carry-'over fingers Ii. On rocking with the lever, the spindle 68 draws backand all the fingers 08 leave the rings 83 and can lift up into theirinitial position against the stop 61 under the action of their springs69.

There now will be given an example for explaining the carry-overoperations in a totaliser, reference being made to Figs. 17a1'7dSupposing the amount previously registered on totaliser A is 349.00 andthe operator wishes to add thereto 23.00. To that end he has turnedthrough two tenths of a turn the "tens disc ll" (Fig. 17d) and this discnow registers 4+2==6. After escapement, the button "A has engaged theunits disc I0, as shown in Figs. 17a, 17b and 17c.

In Fig. 17a, disc It still registers the figure 9. The ring '3 rigidlyconnected with It then is in such a position, with respect to the fingerii, that disc I 0' only has to rotate through one tenth of a turn inorder that the carry over be prepared by the engagement of finger I6 innotch 64. This position is shown in Fig. 17b.

However as the operator has to register not one unit but three units, hedoes not stop disc I! in the position of Fig. 17b but he rotates itthrough three tenths of a turn, thus bringing disc it to the positionshown in Fig. 17c, where the figure 2 is registered (9+3=12). The Figs,17a, 17b and 17c also show the successive positions of parts Iii, 1i and12, the latter in Fig. 170 being in the path of travel of the arms I3.

The operator now turns the crank I5, thus turning shaft 14 and its arms13. One of these arms strikes projection 12 and. causes the piece II torotate still further in the same direction as previously (Fig. 17d)During this movement the tooth Ii has engaged disc II" and caused it torotate through one tenth of a turn, so that it re:- isters the figure 7instead of 6, the required carry over thus having been effected.Immediately thereafter the counter-tooth it engages disc It" andprevents said disc and the piece II from rotating further. The spring llbeing under tension will return piece II to its initial position as soonas the shaft II and stop 81 have been withdrawn as explained before.

It will be seen that the rotation of disc I." through one tenth of aturn, due to the carry over of one unit to said disc, does not cause arotation of bar I! and does not influence the other totaliser discs.

If after committing an error, the operator rotates backwards the ring 03(with its associated disc lll)-see Figs. 17c and l'lb-the notch llallows the finger I, drawn by ring I! and sprin 89, to resume itsinitial position shown in Fig. 17. The carry over which had beenprepared by the downward movement of finger 6 thus is cancelled togetherwith the erroneous operation which had caused the carry over to beprepared.

As has been stated above, the clerk's totalisers A and B are eachflanged by an operation counter A B (Figure 1) constituted of discs llidentical to those of the totalisers. At each operation reg istered by aclerk's totaliser the first disc it of the latter which rotates, lifts,by the action of its teeth on a wide boss ll covering all the discs ofthe totaliser, a spring blade 05 (Figures 19 and 20), the end of which,forming a hook, is thus disengaged from a part similar to the part II ofthe carry over mechanism and mounted like said part II on the spindle08. This piece 96 oscillates, drawn by a spring ll, its tappet ll comesin the path of one of the arms I! which carries it along when the handle15 is rotated, so that a tooth I of the piece ll causes the counter discindicated by II to advance by a tenth of a revolution. As heretoforenoted, Fig. 1 shows, in axial section, the operation counters A on theleft-hand side of totalizer A, and B on the left-hand side of totaliserB. These two counters are identical with each other. Fig. 20 is a topview showing, on a larger scale, one of said totalisers (for example A).

It is seen from Figs. 19 and 20 that the spring blade N, ll is lifted assoon as any one of the discs of the corresponding totaliser is rotated.The piece 9' thus being freed, its spring 91 causes said piece to rotateand bring the tappet it into the path of one of the arms 13 (which isnot illustrated in Fig. 19, but all the arms II are shown in Fig. 8).When the handle Ii is rotated with the shaft II and the arms II thecarry over of a unit to the first disc of the counter is effected in thesame manner as the carry over in the totalisers.

The carry over of tens in the counters takes place in the same mannerand by means of identical parts as the carry over in the totalisers.These parts have not been shown in Fig. 19 in order not to overburdenthe drawing, as it will be understood that they are the same as theparts II, I shown in Fig. 17. Of course, the blades ll, 05 have nothingto do in the carrying of tens in the counters. The carry over of thetens of one disc to the other of the counter is carried out as for thetotaliser, and the return of the driving members and of the carry overmembers to the position of rest, apart from the discs, is alsocontrolled by the rocking of the spindle 68 at the end of the movementof the handle 1|.

.side by side on a spindle head with the sleeve assaosa It will beunderstood that the counter counts a unit at each operation of thecorresponding clerk's totalizer.

The handle or crank 15 controls, directly after each operationregistered by the machine, the printing mechanism intended to print. theamount of the operation ontickets delivered by the register, and tofulfill other functions such as the resetting to zero of the indicator Iafter each operation and of the clerk's and daily totalisers at the endof the day, as also the printing or the amounts totalled by all thetotalisers.

The printing mechanism (Figures 21, 22 and 23) comprises an oscillatingprinting head comprising a series of character discs I00, each providedwith ten teeth IOI and loosely mounted I02 between two uprights I03. Thelatter are cross connected at the foot by a sleeve I04 fitted on to atubular spindle I05 surrounding the spindle 10 of the crank 15, and atthe top by a spindle I carrying a series of toothed wheels I01 of tenteeth each which engage permanently with the teeth IOI of the characterdiscs. Fig. 1 shows on spindle I the sleeve I04 carrying the printinghead. Said I04 can slide along the whole length of spindle I05 which iscoaxial with spindle (Figs. 1, 21, 22).. Fig. 23 shows the printing headin front of totalizer A. The wheels I01 are mounted loosely on thespindle I00 and each can be carried around by it by means of a pin I00forced along by a radial finger I00 of the spindle I06. In thepositional rest of the printing head, the wheels I01 engage with thediscs I0 of the indicator I. Consequently, each value set up on theindicator is reproduced on the printing head, the character discs I00 ofwhich rotate in unison with the discs I0 of the indicator. This rotationof the discs I00 tensions in the boss of each of these a spiral springIIO fixed on the one hand to the wheel, and on the other hand to thefixed spindle I02. As shown by Figure 21, the arrangement of theprinting characters on the edge of the discs I00 (the drawings show themon the side of the disc for greater clearness) is such that the printinghead can effect simultaneously two impressions of a single amount oneach side of the vertical plane passing through its axis I02. Fig. 24shows outside of the large circle the characters which print uponrollers I24 and I25. These characters pass the rollers I24 and I25 inclockwise succession when the character discs I00 turn in unison withthe wheels II) of the indicator. The sleeve I04 of the printing head isin engagement through a pin III with a longitudinal groove II2 of thetubular spindle I05, which extends up to the leit-hand extremity of theregister where it carries a triangular plate IIO (Fig. 10) provided withtwo small rollers H4, H5.

When at the end of an operation the crank is rotated, the pinion 00rotates a cam IIO (Figure 10) which forces back the roller 4 and thuscauses the plate IIO and the whole of the printing head to rock fromright to left about the spindle 10, the uprights I00 being integral withthe plate through the tubular spindle I05 and the sleeve I04. The wheelsI01 disengage from the discs I0 of the indicator (Figure 21) whilst alarge pawl II1, pivoting on the spindle I02, which had hitherto beenkept away from the wheels I01 by the meeting of a bossIIO of the stop H9with a curved nose piece I20 of this pawl, blocks the wheels I01 inorder to prevent the springs IIO from distending.

The printing head strikes, with the interposing of an inked ribbon I2I,two bands of paper I22, I20, passing over two rollers I24, I25 andprintssimultaneously the same amount on the two ribbons due to the suitablearrangement of its characters; Paper feeding and severing means may beprovided such, for instance, as that disclosed in my above mentionedPatent No. 2,282,120.

' After the printing of the tickets, the cam IIO releases the roller Illand a spring I04 (Figure 10) acting on the plate III, raises theprinting head to bring the wheels I01 into engagement with the discs I0of the indicator 1.

Just before this takes place, the upper extremity of the curved nosepiece I20 strikes the stop H0 and this disengages the pawl II1 from thewheels I01. Nevertheless, since the discs I0 are prevented from rotatingcounter-clockwise by their pawls 24 (Figure 1), the wheels I01 remainblocked and the springs IIO remain tensioned. The amount set uptherefore remains shown at the indicator. At the commencement of thefollowing operation, the operator bearing on the pusher 50' (Figs. 1 and13) to permit the spring 50 to bring the spindle I2 into its initialangular position by counter-clockwise rotation, which is now possiblebecause all buttons 00 are completely disengaged from the discs and theselectors, starts at the same time the movement for resetting theindicator to zero. To this end, a lower extension of the pusher 50acting on a part I45 (Fig. 1) which connects all the pawls 24 blockingthe discs I0 of the indicator 1, disengages these :pawls from the discsI0 which are then tree to rotate. The springs I I0 distend causing thecharacter wheels I00 to rotate which wheels through the intermediationof the wheels I01, bring the discs I0 to zero by themselves coming tozero, whenthe pins I00 reach the fingers I00. At the same time there isanother stop when the pins 04' of the indicator wheels reach the stopstrip I55.

There will now be described the operation of resetting the totalizers tozero. Whilst the portion of the printing mechanism which comprises therollers I24, I25 remains at a fixed position under the indicator I, theprinting head IOI, I01 constitutes a carriage which can be moved fromone end to the other of the register by sliding the sleeve I04 along thetubular spindle I05, in order to be brought opposite one or the other ofthe totalisers. These movements of the printing head may be handle I40(Figures 21) which projects through a vertical slot of the outer casingof the register, which slot forms a portion of a grid of slots in thefront wall (not shown) of the outer casing.

The handle I40 is mounted on a lever I41 pivoted on the tubular spindleI05 and coupled to the printing head by the tail of the handle I40engaging in a catch I40 on one of the uprights I02. This lever carriesat the top a rackwith ten teeth I40 which engages with a small pinionI50 keyed on the spindle I00.

When the handle I40 is lowered in the vertical slot of the casing, thelever I41 engaging the catch I40 causes the printing head to swingtowards the position shown in Figure 21 until the roller 5 of thetriangular plate IIO comes into contact with a cam III (Figure 10) whichstops the swinging movement when the wheels I01 are disengaged from thediscs I0 of the indicator. on then pulling outwardly on the handle I40;its

controlled by the operator by means of a g tallv is caused topass overthe catch Ill and it can be further lowered with the lever I", which hasfor the first effect to cause said lever I" to depress a catch I52 andthus to disengage the pawl ill from the wheels I", and secondly toimpart by means of the rack I and the pinion III a complete revolutionto the spindle I which rotates, by its fingers ill the wheels I" andIll. The latter are thereby reset to zero and their springs III arefully wound up. The lowering of the lever is assisted by a spring I" andis limited by a stop I". It isheld in the lowered position by insertingthe tail of the handle I behind a stop I" (Figure 22) formed by anextension of the spindle I".

Still by means of the handle I, the operator then shifts the wholeprinting head horizontally along the spindle I until it comes oppositethe totaliser to be set to zero. This movement of the handle is guidedin a horizontal slot of the cover of the machine. Opposite the desiredtotallaer a vertical slot comes in front of the handle. The operatorcauses the handle to move upward in this slot which has for eifect toraise the printing head, the wheels III! of which come into engagementwith the toothed discs ll of the totaliser. At the same time a bar 83carried by the uprights Ill, Fig. 21 engages the heels N of the pawls 2|appertaining to the discs ll of the totaliser in question, thusdisengaging these pawls from the discs. If the operator disengages thetail of the handle Hi from the stop III, the springs ill distend causingthe rotation of the wheels Ill and II! which rotate the discs llcounterclockwise. As will be understood, this movement of the wheels illand II! is possible because the pawl H1 is held in inoperative positionby engagement of the nose piece III with the stop H8. Each disc ill willrotate until a projection ll of its periphery strikes against a stopstrip I58 on the printing head. The disc I. is then at zero whilst theamount which it indiciated is transferred to the corresponding disc IIIwhich has rotated by the same angle butstarting from zero. This amountor figure transferred will appear at the lower part of the characterdisc III in the vertical plane passing through the axis ill. Thus, inthis case the character discs I" rotate away from the zero position incounter-clockwise direction as shown in Fig. 24 inside the circle. Sincethe same operation takes place for each disc of the totaliser and of theprinting head the amount and if desired the identification lettersregistered on the totaliser are transferred to the printing head wherethey are inscribed in the plane passing through the axis Hi2, whilst theentire totaliser is wholly reset to zero.

If the operator then rotates the crank II, the printing head oscillatesunder the action of the cam H6 as previously described and prints theamount of the totaliser on an account sheet or docket supported by aroller I51 under the inked ribbon ill in the plane passing through theaxis I02.

The operation is repeated for the resetting to zero of each totaliser,and the printing of the amount registered thereby. After the resettingto zero of the totaliser, a spring 85 (Fig. 1'1) attached to the bar 86of the unit ll2l brings each pawl 24 back into engagement with its discIII, to block it.

The disengagement of the pawls 24 which is produced to permit therotation of the discs II in clockwise direction, under the action of thecarryover mechanism previously described, is only possible when the unit"-20 la atthe terminal position of travel towards the right. The aleevell like thepawl I4 iscontrolledbyaaprlngattached to the bar itandwhichtendstorockthesleeve clockwise. In this position the sleeve II,on which are nttedtheeyesofthepawis.isfreetorotate.Whenapawloscillatesunderthethruatofadiac ll rotating clockwise, itcarries the sleeve I. with itbyanotchl'l ofitseyell andarib llofthesleeve (Fig. 23). This latter pivots with the pawl which has oscillated,but its movement does not,

influence the other pawls of the comb, in thd notches ll of which therib I. can freely move.

But when the unit l'|2l is moved towards the left to select and actuatethe totallsers, the sleeve It is prevented from rotating by theengagement of a pin III on the shaft 21 with a slot Ill on said sleeveII (Fig. 2) and it no longer permits the oscillation of the pawls 24during the manipulation of the totalisers by means of the bar l1 and ofthe driving buttons 30. It follows that all the discs of the totalisersare blocked except those which are in engagement with the buttons 30 andopposite which the comb of pawls is interrupted, as explained above.

It is shown by the present description that the cash register accordingto the invention is capable of carrying out a large number of operationswith a comparatively small number of members and devices.
